Extended useage of existing buildings

[grampybear]

After much trial and error (and frustration) I have determined that I can't draw or paint a building,however that said, we already have many fine innercity buildings that currently only work as eye candy,ie: auto dealer and Eugenes fine clothes both by MHz . Without breaking laws and copyrights is there a way to extract the dat and png file from game and change dat file to "factory" so that city building could now receive goods and be more than a nice looking building?

MHz's graphics are available for public use... for download, see:

Thank you. This file has more than I need to create more inner city "factories" having a small footprint. You guys are the best.
